Some people also use olive oil to boost bacteria in the gut and as a “cleanser” or “purifier.”

Side-Effects & Allergies of Olive Oil

Side effects of olive oil includes acne (if used excessively), can show acute allergic reactions in people sensitive to it, skin rashes, breaking the skin’s natural moisturizing abilities in case of dry skin, blackheads, inflammations, gall bladder stones, minor to moderate diarrhoea.

The Olive oil lowers the blood sugar level below normal and may lead to health problems like hypoglycemia, sweating, trembling, weakness, etc.

Pregnancy and breast-feeding

Olive oil might affect blood sugar. Using olive oil might affect blood sugar control during and after surgery. Stop taking olive oil 2 weeks before surgery.

Can cause allergies

Several people show acute allergic reactions to olive oil. And if you are one of them, I would suggest you stay away from it—this oil will only aggravate your condition.

Causes skin rashes

As explained earlier, people with oily skin should avoid olive oil altogether.

Oily skin is the result of an uncontrolled sebum secretion. When olive oil combines with your naturally greasy skin, it can cause severe irritation, rashes, and redness on your skin.

Can Cause Blackheads

With its extremely sticky and oily nature, olive oil can pave the way for the growth of blackheads on your face.

As explained earlier, the greasy olive oil forms a layer on your skin that traps in the dirt and dead skin into it. This, in turn, makes way for the formation of blackheads.


The high fat content of olive oil may cause digestive disorders and trigger gastrointestinal problems like diarrhea. When we consume it in large amounts, our system becomes unable to digest it completely.

As a result, we develop minor to moderate diarrhea. Being a natural laxative, oil sometimes makes the situation worse.

Weight gain

There is a myth that olive oil is a healthier alternative to other conventional cooking oil, and it is extremely helpful in maintaining the ideal body weight.

Yet, the truth is that it is a fat-rich food that actually contributes to our body weight.

Unnecessary weight gain is one of the major side effects of too much olive oil consumption.
